Heartstopper: parents' guide

Rated strong for one sexual assault: in season 1, Charlie's secret ex pins him to a wall and forces a kiss on him while he says stop, until Nick pulls him away. Otherwise some scuffles with bullies and a black eye.

Mostly British slang such as "piss off" and "knob," with occasional s-words, "dick" and an f-word here and there in later seasons. Bullies use a homophobic slur, and a hateful message tells Charlie being gay is worse than being dead.

Kissing and making out between teen couples, a visible hickey and teens lying in bed clothed. In season 3 the two boys have sex for the first time, in non-explicit scenes where Charlie keeps his shirt on. A teachers' hookup is implied.

Teens drink at a hotel party on a school trip in season 2, and at least one drinks until sick. In season 3 Charlie gets drunk at his birthday party and tells Nick he feels ready for sex. No drug use or smoking is reported.

Season 1 shows Charlie bullied, once wondering aloud if he should just disappear. Season 3 follows his eating disorder worsening, a self-harm relapse and a stay in an inpatient clinic. A friend has a panic attack, and another leaves home after a fight with her homophobic mother.
